Abstract
A carbon fiber is oxidized to form oxygen-containing functional groups on the entire surface of the fiber and then contacted with ammonia, an organic amine, a lactam, or an amino carboxylic acid at a temperature of 100.degree.-500.degree. C whereby the surfaces of the carbon fiber obtain good affinity for a synthetic resin.
